Abstract
The utility model discloses a diffusion type LED (Liquid-Emitting Diode) display screen, which comprises an LED module, wherein the LED module consists of a PCB (Printed Circuit Board) and a plurality of LED units which are arranged in sequence on the PCB; the side face of the PCB which is provided with the LED units is provided with a plurality of circular concave pits; the LED units are fixed in the concave pits; the concave pits are provided with diffusion covers; and the diffusion covers consist of connecting barrels which are in threaded connection with the concave pits, and spherical diffusion covers which are used for diffusing light rays emitted by the LED units. According to the diffusion type LED display screen, light rays emitted by the LED units are scattered by using the diffusion covers, so that the light emitting areas and light mixing areas of the LED units are enlarged, dark region area is reduced, the uniformity of picture brightness is improved, and the display effect is enhanced.
Description
Technical field
The utility model belongs to the LED display technical field, is specifically related to a kind of diffused LED display.
Background technology
Development along with the LED technology, the application of LED display is also more and more extensive, especially outdoor display screen is widely used in station, harbour, airport, market, hospital, bank and other public place, is used for display graphics, literal, letter and various animation.Existing LED display generally comprises some LED unit of arranged in sequence on pcb board and the described pcb board, usually the spacing between the LED unit is more than or equal to the size of LED unit itself, when the LED unit is lighted, brighter in the middle of its light-emitting zone presents, the feature that the edge is darker.Outside light-emitting zone, there is non-luminous dark space, thereby causes picture disply discontinuous, affect display effect.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and a kind of diffused LED display is provided, and it can avoid dark space in the light-emitting zone, has strengthened display effect.
The technical scheme that the utility model adopts is: a kind of diffused LED display, comprise led module, this led module is by some LED cell formations of arranged in sequence on a pcb board and the described pcb board, the side that is provided with the LED unit on the described pcb board is provided with some circular pit, described LED unit is fixed in the described pit, described pit is provided with diffuser cap, and described diffuser cap consists of by the connecting cylinder that is threaded with described pit and with the light diffusion shell that spread, spherical shell shape that described LED unit is launched.
As preferably, described diffusion shell is made by transparent material.
As preferably, be coated with diffusion layer on the outside surface of described diffusion shell.
The beneficial effects of the utility model are: the light that the utility model comes scattering LED unit to launch by diffuser cap, the light-emitting zone and the mixed light that enlarge the LED unit are regional, reduce the dark space area, have improved the homogeneity of picture brightness, have strengthened display effect.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the diffuser cap structural representation.
Among the figure: 1, pcb board; 2, LED unit; 3, pit; 4, diffuser cap; 41, connecting cylinder; 42, diffusion shell; 43, diffusion layer.
Embodiment
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of diffused LED display, comprise led module, this led module is made of some LED unit 2 of arranged in sequence on a pcb board 1 and the described pcb board 1, the side that is provided with LED unit 2 on the described pcb board 1 is provided with some circular pit 3, described LED unit 2 is fixed in the described pit 3, described pit 3 is provided with diffuser cap 4, described diffuser cap 4 is spread by the connecting cylinder 41 that is threaded with described pit 3 and light that described LED unit 2 is launched, the diffusion shell 42 of spherical shell shape consists of, described diffusion shell 42 is made by transparent material, is coated with diffusion layer 43 at the outside surface of diffusion shell 42.
The light that the utility model comes scattering LED unit 2 to launch by diffuser cap 4, the light-emitting zone and the mixed light that enlarge LED unit 2 are regional, reduce the dark space area, have improved the homogeneity of picture brightness, have strengthened display effect.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, the equivalence of namely doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
